Question

simplify & express w/positive exponents (-a^2b/2b^-1)^3

Answer 1

\[\Large\frac{-a^{2b}}{2b^{-1}}\]
is it like that ?

Answer 2

yes and it is all ^3

Answer 3

so lets get to expressing it in positive exponents first right? so lets pull that b up to \[-a ^{2b}*2b\]

Answer 4

now lets distribute that exponent! The rule with exponents on exponents is multiplication right? so multiply it and you;ve got your answer!

Answer 5

wups! -a^(2b)b/2
